Quantitative evaluation method of mine gas disaster hazard sources based on AHP-FCE Method

In order to effectively overcome the index weight provided with subjectivity based on experiences of the experts existed in the fuzzy comprehensive eval uation method applied to the high hazard source evaluation of the coal mine gas disaster in China, the AHP Method and the fuzzy comprehensive evaluation method we re combined and applied to the optimization of the mine high hazard source safety index system and to establish a new safety evaluation method AHP-FCE Method of t he mine high hazard sources. With the application of the actual evaluation data of 60 coal mine enterprises in Hunan Province, a self developed prototype system was a pplied to verify the method.The results showed that the index system determined with the AHP-FCE Method could fully fit with the weighting and theoretical analysis an d could have the good effect of the quantitative and high explanation advantages in the quantitative evaluation of the mine actual gas disaster hazard sources. The high hazard sources distinguished with AHP-FCE Method was same to the results provided by the experts.
